large scale may develop. It is very probable, however, that an
analytical and practical examination of the English experiments noted on
pages 379 and 380, will be sufficient to develop this fact conclusively.

The writer is forced to conclude that some of the criticisms by Mr.
Goodrich result from a not too careful reading of the paper. For
instance, he states:

"'It is conceded' (line 2, p. 357, for example) when the writer,
for one, has not even conceded the accuracy of the assumptions."

A more careful reading would have shown Mr. Goodrich that this
concession was one of the writer's as to certain pressures against or on
tunnels, and, if Mr. Goodrich does not concede this, he is even more
radical than the writer.

And again:

"'Nor can anyone * * * doubt that the top timbers are stressed more

earnestly denied by the writer."

It is unfortunate that Mr. Goodrich failed to make the complete
quotation, which reads:

"Nor can anyone, looking at Fig. 5, doubt," etc.

A glance at Fig. 5 will demonstrate that, under conditions there set
forth, the writer is probably correct in his assertion as relating to
that particular instance. Further:
